M. V. MILLER, OF MANCHESTER, PENNSYLVANIA, AND GEORGE HENRY, OFSTEUBENVILLE, OHIO.

IMPROVED AXLE-BOX.

Specification forming part of Letters Patent No. 56,977, dated August 7,1866..

To all whom it may concern:

Be it known that we, M. V. MILLER, of.

Manchester, in the county of Allegheny and State of Pennsylvania, and G.HENRY, of Steubenville, in the county of Jefferson and State of Ohio,have invented certain new and useful Improvements in RailroadAxle-Boxes; and we do hereby declare that the following is a full andcomplete description of the same, reference being had to theaccompanying drawings, making a part of this specification, in which-Figure 1 is an end view of the axle-box. Fig. 2 is a transverse verticalsection through the same. Fig. 3 is a view of the under side. Figs. 4and 5 will be referred to in the description.

Like letters of reference refer to like parts in the different views.

Our improvement relates to a railroad axlebox so constructed andarranged that it is kept in close contact with the wrist or journal ofthe axle as the box and journal may wear away, and also to the manner ofconstructing the box so that the Waste and oil cannot work out or dustand dirt enter the box, as hereinafter described.

A, Figs. 1 and 2, is a case in which the journal box or seat B B isplaced. X is the axle and its journal. The box is fitted into the caseand prevented from moving sidewise by means of tongues or projections Gon the sides, (seen in Figs. 2 and 4,) fitting into correspondinggrooves (Z in the case. In the lower part, B, of the box are holes E E,Fig. 2, in which spiral springs F F are placed. The upper part of thesprings are in the holes, and the lower end rests in stops G, which areout or grooved out for this purpose. These stops are supported on aplate, H, shaped as shown in Fig. 3, the ends of which fit and slide ingrooves c in the sides of the case. (Seen in Fig. 3.) The stops G areheld in place on the plate by a pin or projection, c, at the inner end,fitting into a hole in the plate, and there is a tongue or projection,12, at the outer end, that fits into the grooves 01 in the case, asshown in Fig. 3, which holds them in place, and also prevents the plateH from having any lateral movement.

The object of this arrangement of the springs is to keep the box or seatB B constantly in close contact with the journal or wristas they maywear away by rubbing and wearing on each other. The elasticity of thesprings will produce this, as the lower half, B, of the box is fitted inthe case 'so that it can be moved up or down by the action of thesprings keeping the box and journal in close contact with each other.

In the lower part of the box there are chambers J. (Shown in Fig. 4,which is a top view of this part of the collar detached, and also inFig. 5, that is a vertical section through a part of the box and case.)These chambers communicate with each other through openings or holes is,(seen in Fig. 5,) and are for holding the waste caused by the wearing ofthe journal and box as it may accumulate, and also for holding oil. Theribs or partitions n a, between the chambers, prevent the Waste fromturning in the box, also preventing, by this means, the wearing of thejournals and boxes by the grit and dirt.

The waste and oil cannot escape from the ends of the box, on account ofprojections m, at each end of the lower part of the box, fitting intocorresponding recesses u in the upper part, as seen at L in Fig. 5, thusbreaking the joint where the upper and lower part of the box unite, thatprevents the oil from running out and dust and dirt from working intothe box.

What we claim as ourimprovement, and de sire to secure by LettersPatent, is

1. The plate H, stops G, in combination with the springs F,journal-box BB, and case A, when arranged as, in the manner, and for the purpose setforth.

2. The combination of case A, journal-box B B, axle or journal X,springs F F, stops G. and plate H, constructed and arrangedsubstantially as shown and described, and for the purpose set forth.
